Peppe calculates its weight, lid included, at 1537 Ib.
Thus if it calculates the result of some experiment, it is not the experimentalist's well-attested results which are on their trial, but the basis of the calculation.
Mohn has shown how the inequalities of what he terms the densitysurface can be found from the salinity and temperature; and he calculates that the level of the Skagerrak should be about 2 ft.
Kriimmel calculates that the mean temperature of the whole ocean surface is 63.3° F., while the mean sea-level temperature of the whole layer of air at the surface of the earth is given by Hann as 57.8 ° F.
Sir John Murray calculates that at least 80% of the water in the ocean has a temperature always less than 40 F., and a recent calculation by Kriimmel gave in fact a mean temperature of 39° F.
